Development of Green Marketing Mix Model with Emphasis on Evaluating Purchaser's Intentions in the Field of Energy (Iran's Oil and Gas Industry)

In the new century, consumer concerns about environmental accountability, which are also aligned with environmental laws, have pushed a growing number of companies to design and create environmentally friendly programs. Accordingly, this study examines how to implement a green marketing mix to sell a product and stay in the market. Based on this, a sample of 90 investment marketing specialists in the field of green marketing in the field of energy was randomly selected and examined according to the volume of each category. The conceptual model of the research was designed based on the combined theoretical studies of green marketing and consumer intention and based on it, questionnaires were designed and the desired data were collected. The results show that in order to research the objectives of the research, the following items should be considered in such a way that they can compete with similar types: the use of recyclable materials to produce the product to reduce environmental damage, the introduction and presentation of environmentally friendly energy in exhibitions, conferences and seminars, the use of update transportation system to distribute products in the market to do less harm to the environment, appropriate pricing of green products

Behavioural and molecular study of the effects of rosuvastatin on acquisition and retention of spatial memory impaired by H-89 in rats

There is controversy on the effect of statins on cognitive functions such as spatial memory. In the present study, effect of ten- day oral gavage of rosuvastatin (Ros, 20 mg/kg) on spatial learning and spatial memory retention impaired by H-89, was investigated in male rats. This study was comprised of two sets of experiments each including the following 3 groups (n = 8): Control group treated with DMSO; H-89 group received bilateral intra-hippocampal H-89 (10 μM/side, in DMSO) and Ros- H-89 group orally treated with Ros (20 mg/kg) and H-89 (similar to the H-89 group). For spatial learning (acquisition phase) assessment, from day 7 of Ros gavage, rats were trained in the Morris water maze (MWM) for four days (one block of 4 stages each day) and received daily H-89, 30 min after Ros gavage. On day 11, the probe test was performed. Also, to assess spatial memory retention, from day 7 to 10 of Ros gavage, rats were trained in MWM but received H-89 on day 10 only. On day 12, the probe test was performed. Besides, CREB and p-CREB protein expression was assessed in hippocampal samples and oxidative stress status was assessed in serum samples. We observed that H-89 led to a clear impairment of the spatial learning and spatial memory recall, increased levels of lipid peroxidation and downregulated CREB and p-CREB proteins, compared to the control group. However, Ros prevented H-89-induced deleterious consequences which might be probably in part due to its ameliorative effects on lipid peroxidation index and CREB and p-CREB expression

Significance of Elevated Blood Metal Ion Levels in Patients with Metal-on-Metal Prostheses: An Evaluation of Oxidative Stress Markers

It is widely known that cobalt and chromium ions can enhance the production of reactive oxygen species, known to be damaging to cells by disturbing their redox status and then generating oxidative stress. The aim of the present study was to determine if increased metal ion levels induce a state of oxidative stress in patients with metal-on-metal (MM) hip arthroplasty. Results indicated that there was no significant difference in the concentration of oxidative stress markers (total antioxidants, peroxides, and nitrated proteins) in the patients with MM bearings compared to patients without prostheses. The activity antioxidant enzymes was stable (catalase and glutathione peroxidase) or slightly decreased (superoxide dismutase and heme oxygenase-1) over time. This work is the first to determine the biological effects of metal ions released from MM hip implants with regards to mid-term systemic oxidative stress and showed that the increased levels of Co and Cr ions are not associated with significant oxidative stress damage in the plasma of patients with these implants
